Title:
CONVERSION OF BENZENE INTO OTHER AROMATIC HYDROCARBON
Document Type and Number:
Japanese Patent JP3472184
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To alkylate benzene to convert into other aromatic hydrocarbons in one step by bringing the benzene into contact with a lower paraffin in a specific weight ratio in the presence of a crystalline ZSM-5 type metallosilicate catalyst at a specific temperature in a specific pressure condition.
SOLUTION: This method for converting benzene into other aromatic hydrocarbons comprises bringing the benzene into contact with a 2-4C paraffin (for example, ethane or propane) in a weight ratio of 1:2 to 1:15 in the presence of a crystalline ZSM-5 type metallosilicate catalyst at a temperature of 300-470°C at a pressure of 100-2,500 kPa. The crystalline ZSM-5 type metallosilicate catalyst preferably contains one or more kinds of elements selected from gallium, tin and lanthanum in addition to aluminum in the crystal skeleton, and carries platinum as a carried metal in a concentration of about 0.01-1 wt.%. The contact of the catalyst with the benzene and the 2-4C paraffin is preferably carried out in a fixed bed flow reactor, while decoking and recycling the catalyst which has been used for the conversion reaction and on which cokes have been deposited.
